Hobbes discusses demonology and other relics. Back in the beginning chapters, Hobbes writes about vision and imagination. Anything that a person has seen in his or her life is stored as a memory and these memories can be brought back up at any given time, either in wakefulness or in a dream. People in the past did not understand the process of sight, memory, imagination, and dreams. So anything that their memory brought up and may have misconstrued, they attributed to demons, some good and some bad. The Grecians began the notion of demons and it spread to many cultures. By the time the Jews believed in demons, they got rid of the good ones and believed that all demons were bad.

There is no mention anywhere in the Scripture of demons or people being possessed by them. God does not mention demons...
